1) System clock reset (possibly by synchronizing with a time server)
2) As I recall, touch can alter the timestamp to a particular value.
3) Windows xcopy has a option to do a 'perfect' copy, with timestamps and
permissions intact - over existing files.
4) Buggy/experimental filesystem driver.
5) Some backup/restore programs will restore the original timestamp.
6) Explicitly screwing around with the filesystem APIs for proprietary

I'm sure I can think of a few more cases if you really need them. I've
already been bitten by cases 3 and 5, by the way, as we do a nightly import
of the production web server contents into a branch in the repository.
